Purchased a 2.5GB for 30 days plan around 10/08, expires on 10/09. For the past few weeks, the Internet connection comes and goes OFTEN. It would still show 4G/3G but there would be no Int. conn. Would need to switch airplane mode on and off to get it back but then it would lose conn. again after few minutes. Usually happens when inside building or just driving around or even in a particular spot that should NOT have any problem receiving signal (no such problem exist before this current purchase). Please advise.

Have you check your APN setting running 3G or 4G setting, previously my friend had the same issue and i checked he uses 3G setting but signal show 4G and the internet is very slow. After updated to the latest 4G APN setting everything back to normal.
